Mobile Friendly Authentication
Internet
Built-in
Authentication
Remote access to
subscription databases
is done through OCLC’s
EZproxy Authentication
and Access software.

How to make EZproxy Mobile Friendly
Incorporate a mobile
device detection library?

EZproxy Ticket Authentication

“Ticket authentication allows remote systems to
short-lived URLs that EZproxy will automatically
recognize as being authorized to login and permit
access to a resource with no need for EZproxy to
check back with the program that creates the
URL.” – OCLC website

Sample PHP code
<?php
require("ezproxyticket.php");
$ezproxy = new
EZproxyTicket("http://ezprox
y.yourlib.org:2048", "shhhh",
"someuser");
?>
<a href="<?php
echo($ezproxy-
>url("http://www.somedb.co
m")) ?>">Some
Database</a><br />

Central Authentication System (CAS)
Central Authentication Service (CAS) is a login
service that allows you to access multiple
password-protected web systems after logging
in once on a central authentication server; this
is often referred to as single sign-on.
http://www.jasig.org/cas

CAS vs IU CAS
Standard CAS response – XML
<cas:serviceResponse xmlns:cas='http://www.yale.edu/tp/cas'>
<cas:authenticationSuccess> <cas:user>username</cas:user>
<cas:proxyGrantingTicket>PGTIOU-84678-8a9d...
</cas:proxyGrantingTicket> </cas:authenticationSuccess>
</cas:serviceResponse>
IU CAS response –
If validation is successful, CAS sends back a two-line response with
'yes' on the first and 'username' on the second.

Connecting Ezproxy with IU CAS
1. Detect mobile or desktop
• http://detectmobilebrowsers.mobi/
2. Set CASSVC (service)
• If detect mobile, set service to mobile
3. Check with CAS to see if already
authenticated
4. If authenticated, display database; otherwise
present a login screen

Sample Code – login.php
<?php
include('mobile_device_detect.php');
if(mobile_device_detect(true,true,true,true,true,true,false,false)){
header("Location: https://cas.iu.edu/cas/login?
cassvc=MOBIU&casurl=https://www.domain.edu/~site/cas/casauth.php");
}else{
header("Location: https://cas.iu.edu/cas/login?
cassvc=IU&casurl=https://www.domain.edu/~site/cas/casauth.php");
}
?>

Sample Code – casauth.php
<?php
session_start(); //start session
if( isset($_GET['casticket']) ){ //check to see if a ticket has been passed
$ticket = $_GET['casticket'];
} else {
$ticket = "";
}

Sample Code – casauth.php cont.
/*
* check CAS ticket authenticity and get the user's uid back
* the variable $contents will have the string
* "ticket '<ticket value>' not recognized" if a bad ticket
* has been provided.
*/
$casXML = fopen("https://cas.iu.edu/cas/validate?
cassvc=IU&casticket=$ticket&service=https://www.domain.edu/~site/cas/c
asauth.php","r");
$contents = fread($casXML, 1024);
fclose($casXML);

Sample Code – casauth.php cont.
list($yesno, $netid) = split("n", $contents, 2);
$authok = trim($yesno);
$iuid = trim($netid);
if ($authok == "no") {
header("Location: https://www.domain.edu/~site/cas/login.php");
}
else {
$_SESSION['auth'] = $iuid;
header("Location: https://www.domain.edu/~site/cas/success.php");
}
?>

A Better Idea – Can IU Mobile do it?
IU Mobile is already connected to IU CAS
Need ability to
• Check if authenticated
• Display alternative information if not
• Restrict to campus level

Yes, IU Mobile Can do it!

Authenticated vs. Not-Authenticated

Sample Restriction to South Bend
<list-item>
<authenticated>
<if permission="southbend">
<link type="external" url="<?php echo($ezproxy-
>url("http://vnweb.hwwilsonweb.com/mobile/jumpstart.jhtml")) ?>"
title="HW Wilson" />
</if>
</authenticated>

$region_location = $region['location'];
$region_mac_status_counts = get_status_counts_for_region($region_id, 'Mac');
$region_pc_status_counts = get_status_counts_for_region($region_id, 'PC');
$total_idle_mac_computers = $region_mac_status_counts['idle'];
$total_busy_mac_computers = $region_mac_status_counts['busy'];
$total_idle_pc_computers = $region_pc_status_counts['idle'];
$total_busy_pc_computers = $region_pc_status_counts['busy'];
$total_idle_computers = $total_idle_mac_computers + $total_idle_pc_computers;
$total_online_computers = $total_idle_computers + $total_busy_computers;
print "<seat lab="$region_building $region_location"
building="$region_display_name" availability="$total_idle_computers/
